Be less pessimistic

Everybody has his or her own flaws. Nobody is really considered perfect. Imperfections in my life does not mean I am a failure but it just means that I have gone through a lot of challenges. I noticed that I have gotten stronger and mroe confident in dealing with people and issues. I can not expect my life to be any easier than it should but I could always make it easier for me and stop putting pressure on myself. I believe that I am more unhappy because I have expect too much of myself. Like many said you are the worst and hardest peron to please.

How can I be less pessimistic? I always preffer to expect the worst than hope for the best. I know that in some cases that this is a good idea but either way it is better to think positive. But like I just said how can you not worry what to do next when you hate surprises and you preffer to be prepared on anything especially the bad ones. I think this will be the hardest for me.
